如何在java中实现列表ADT

import java.util.List;

public class MyList<E> implements List<E> {
    private E[] elements;
    private int size;

    public MyList() {
        elements = (E[]) new Object[10]; // 初始容量为10
        size = 0;
    }

    @Override
    public boolean add(E element) {
        if (size == elements.length) {
            // 扩容数组
            E[] newElements = (E[]) new Object[elements.length * 2];
            System.arraycopy(elements, 0, newElements, 0, size);
            elements = newElements;
        }
        elements[size++] = element;
        return true;
    }

    @Override
    public void add(int index, E element) {
        if (index < 0 || index > size) {
            throw new IndexOutOfBoundsException();
        }
        if (size == elements.length) {
            // 扩容数组
            E[] newElements = (E[]) new Object[elements.length * 2];
            System.arraycopy(elements, 0, newElements, 0, size);
            elements = newElements;
        }
        System.arraycopy(elements, index, elements, index + 1, size - index);
        elements[index] = element;
        size++;
    }

    @Override
    public E get(int index) {
        if (index < 0 || index >= size) {
            throw new IndexOutOfBoundsException();
        }
        return elements[index];
    }

    @Override
    public int indexOf(Object element) {
        for (int i = 0; i < size; i++) {
            if (element.equals(elements[i])) {
                return i;
            }
        }
        return -1;
    }

    @Override
    public boolean remove(Object element) {
        int index = indexOf(element);
        if (index != -1) {
            remove(index);
            return true;
        }
        return false;
    }

    @Override
    public E remove(int index) {
        if (index < 0 || index >= size) {
            throw new IndexOutOfBoundsException();
        }
        E removedElement = elements[index];
        System.arraycopy(elements, index + 1, elements, index, size - index - 1);
        elements[--size] = null;
        return removedElement;
    }

    @Override
    public int size() {
        return size;
    }

    // 其他方法的实现...
